Raspberry Pi 5 and GPIO TPM

I suspect you mean SPI, or maybe i2c, generally TPM modules don't work
directly with GPIO.

Currently, on the RPi5, I don't believe this is possible. I'm not
100%, but I believe the SPI on the 10 pins header uses the SPI on the
RP1, and that's still being wired up, so it'll be a while.

The recent patches I believe you're referring to are the PCIe ones,
they are the first step towards, RP1 core support.
